Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 32,168,275, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 32,168,275 | |
| -1 | -32,168,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,168,275.
Example:
1 x 32,168,275 = 32,168,275
and
-1 x -32,168,275 = 32,168,275
Notice both answers equal 32,168,275
With that explanation out of the way, let's continue. Next, we take the number 32,168,275 and divide it by 2:
32,168,275 ÷ 2 = 16,084,137.5
If the quotient is a whole number, then 2 and 16,084,137.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,168,275 | |
| -1 | -32,168,275 |
Now, we try dividing 32,168,275 by 3:
32,168,275 ÷ 3 = 10,722,758.3333
If the quotient is a whole number, then 3 and 10,722,758.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,168,275 | |
| -1 | -32,168,275 |
Let's try dividing by 4:
32,168,275 ÷ 4 = 8,042,068.75
If the quotient is a whole number, then 4 and 8,042,068.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,168,275 | |
| -1 | 32,168,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 113 | 193 | 295 | 565 | 965 | 1,475 | 2,825 | 4,825 | 6,667 | 11,387 | 21,809 | 33,335 | 56,935 | 109,045 | 166,675 | 284,675 | 545,225 | 1,286,731 | 6,433,655 | 32,168,275 |
| -1 | -5 | -25 | -59 | -113 | -193 | -295 | -565 | -965 | -1,475 | -2,825 | -4,825 | -6,667 | -11,387 | -21,809 | -33,335 | -56,935 | -109,045 | -166,675 | -284,675 | -545,225 | -1,286,731 | -6,433,655 | -32,168,275 |
